Mars, sometimes called the red planet, is the fourth planet from the sun. Its surface is made up of iron, which is why it looks red. Mars is only about half of the size of Earth and is too cold for humans to live on, although in some parts of Mars, it can be warm during the day. Like Earth, Mars has been found to have ice at its north and south poles. Unlike Earth, Mars has not one, but two moons! Its moons are named Phobos and Deimos.

Scientists believe, from the information gathered by the Viking spacecraft, long ago, when the volcanoes were active Mars had a thicker atmosphere, which allowed liquid water to run in rivers, lakes and seas. This is evidenced by valleys undoubtedly caused by running water.
Once the volcanoes became extinct the once thick atmosphere leaked away, leaving only the thin carbon dioxide filled air. The water either boiled away or froze into the ground, thus the polar ice caps contain a mixture of frozen water and CO2, Mars is indeed a planet in a deep freeze!

Mars is a topic of conversation many scientists have been invested in for the past few centuries. There has been historical evidence found that astronomers had been drawing maps of Mars since 1860s.
Is there a life on Mars? If you have a chance to go to a country side where you may have a clear view of the sky at night, you probably will discover a red star. That is probably Mars.In 1877, astronomer Giovanni Schiaparelli discovered several crisscrossing lines on Mars that he believed to be the canals of water.
Go along with the hypothesis that life existed on Mars, several processes has been made to prove hypothesis. However, is there really lives on Mars or people are just wasting their times and money to prove the thing that never exists?.
